Before assembling signatures into a group that is later to become a book it is customary, under certain conditions, to tip or paste asingle toa signature and'to place this combined signature and single in the hopper of a gathering machine Where it is then gathered in the usual Way with other signatures. The tipping is therefore a separate operation that precedes the gathering operation andis performed iii a separate machine. So likewise before assembling signatures7 especially for books that are intended to be bound in cases, it is `customary to tip one signature yto another; the signatures so tipped being the end signa-ture and the' one next adjacent the-reto at both the beginning and end of the book.

rthe present process may be used'in performino`v this Work, and the tipping device herein disclosed may be used as a Separate machine independent of any other mechanisin, but preferably, and as herein described and illustrated, the process of signature gathering piecedes the tipping process and the construction of the gathering machine is coordinated With that of the tipping de vice, and

this is one of themost important features of this invention. v

Considering first the process of tipping per se7 Without regard to the gathering inachine, attention is directed to Fig'la in which c indicates a signature or a` signature group and and c indicate other signatures. It Will be noted that signatures a and Z), for instance,

are out of alineinent with each other thereby exposing a portion of that side of one signature which is adjacent to anotiier signature; rPhe signatures may occupy a fiat position but in this instance both a, b and. o occupy an uprighty position With their vbacks loiverniost in Which position theyare advanced by suitable nieans, andthe backs of the signatures are at different levels, a occupying level Z and b and 0 occupying level e. in the present showing a is a signature group constituting the main body of the book and b and c are the end signatures. For the purpose of the present discussion it is 'however suicient to consider a and as being merely two signatures. Owing` to the difference in level of tance from the back of said other signature.

[ill

Considering now a. to be a signature group and and c to be end signatures it will be vevident that the signature group is advanced at a lower level than are the end signatures, and that therefore adhesive my be applied to the exposed portions of the outer sides of the outermost signatures of the group and thereafter the signature group and the end signatures are brought to substantially the same level and pressed together.

Considering the process as being one not merely oit tipping, but also as being one ot gathering it will be understood that the process involveson setting a plurality et signatures into a group constituting the main body of the book and then tipping an end signature on the outermost signature at both sides of the group. Or, to state the matter still differently, the method of assembling' the book consists ot bringing signatures into side by side relation, and then tippingl the end signatures to the adjacent outer signatures of the main body of signatures.

Considering the method of gathering per se this also involves an improvement. As

will be seen from Fig. 1() the signatures are piled in such a way that the end signatures Z) and c are separated from the main body a of signatures, said end signatures lying in separate channels as shown. Or considering a and 7) as being merely tivo signatures they are piled in separated condition.

NOW all these processesfmay be carried on bv hand and may bc used singly or togijether, liiit under modern conditions ot bookn'iaking it is preferable to carry them on, either partly or wholly, by inachinei'y, and accordingly the machines that are to be presently described have been devised.

Referring first to Figs. 1 to 10 inclusive 1 indicates a gatheringmachine such as the well known Juenfst gathering machine provided with a series of hoppers 2 and grip per arms 3, the latter of which takes signatures from the hoppers and places them in raceway 4. Raceway 4 consists of a main central channel 5 and recuinbent inwardly opening end channels 6 and 7. Adjacent the y hopper of the first signature, which is at the end of the gathering machine farthestfrom the Vtipping device, there is located an inclined support 8 above the main support 9 the tirst signature is placed by a gripper arm upon inclined support 8 and auxiliary support 12, its folded back, if any there be, being on support 12. Chain 13 now engages the tail end oi' the signature and moves it to the lett in Fig. 5 under guide 11 and into channel G. The main body of signa-tures t are now gathered one by one in superimposed relation resting on niain support 9 and on top ol' channel 6 as will be most readily apparent from Fig. 10, and both signatures 7) and ci are advanced a unit by chain 13. y

Adjacent the hopper of the last signature c, that is nearest the tipping machine 7, S, 9 and 10) there is an inclined support 14 acove main support- 9; an auxiliary support 15 for the folded bacl; of the signatures. said auxiliary support extending into channel 7 which latter' begins at point designated by 16. 17 indicates an upper flaring guide eX- tending from, channel 7 and in yspaced relation to auxiliary support 15. Channel 7 eX- tends through the tipping device. It will now be understood that signature c is placed by a gripper arm on supports 14 and 15 and as signatures e and b are advanced beneath said supports the chain will engage the ail end ot signature c and will move it toward the lett in Fig. 7 into channel 7. Thus the signatures are gathered in separated relation.

Referring now to Figs. 1 to 4 inclusive there is located intermediate gathering machine 1 and tipping machine 18 a spiralrace way 19 similar to the one disclosed in U. S. Letters Patent No. 846 923, dated March 12, 1907, the details oi which are not shown and it will be understood that this spiral raccway forms a continuation of the gathering ii'iachiiie raceway and that. not only is the main channel twisted but the end channels (5 and 7 and the conveyer chain 13 are likewise twisted. Suitable upper guides similarly twisted are also provided. The function ot the .spiral is to move the signatures trom a latwise into an upright position. For the sake of clearness the twisted portion ot channels 6 and 7 are broken' away inmost of the drawings.

One form of tipping machine is shown in Figs. 1 to 4 inclusive and Figs. 11 to 14 inclusive. In tl e form there shown 2O indicates a main bed. Arranged on the upper surface and centrally thereof and in spaced and parallel relation with each other, are channels 6a and 7n occupying an upright position which form continuations of recumbentchannels 6 and 7 of the gathering machine and the space 5 between these channels forms a continuation of the main channel 5 of the raceway 4 of the gathering machine. nels 6EL and 7a are carried by transversely adjustable brackets 21 which are slotted to receive bolts to thereby adjust the machine to different thicknesses of signature groups. 24 indicates lower inner guides carried by channels4 6a and 7 a to guide the lower backs of the signatures of the group where they enter the machine on'account of the difference in level between the top of the bed over which the signature group slides andthe inside bottom surface of the channels 6a and 7a. 25 indicates upper inner guides separating signature group o from signatures b and c. These guides are. conveniently pendent guides carried by longitudinal angles 26 adj ustably bolted in ay transverse direction by means of bolts 27 in slots 23 of transverse bars 29. There are here two transverse bars 29, which support longitudinal angles26, and said bars Aare carried by four uprights 30. 31 are longitudinally extending upper outer guides to support the upper end of the end signatures, and these guides are carried by arms 32 transversely adjustable in bushings 33 of uprights 30. 34 indicates a' ramp carried by supports 35 centrally of the upper surface of bed 2O to bring the main body of signatures to the same level as the end signatures after adhesive has been applied. 36 indicaties adhesive applying wheels located adjacent to the infeed end of the tipping machine, that is at the right in Figs. 11 and 12. These adhesive applying wheels rotate in a horizontal plane and extend in beneath channels 6EL and 7a and through lower' inner guides 24 so'as to engage the exposed surface of the outer signature of the signature `group and apply a line of adhesive thereto. Each of said wheels 36 is mounted on an upright shaft 37 carried byv a slide 33 transversely adjustable in guides 39 of the main bed so as to permit adjustment tov compensate for adjustment of the channels 6 and 7. 4() is a clamping bar and 41 are bolts to retain the slide in the position to which it has been adjusted. 42 is an adhesive container in which wheel 36 rotates and from which it receives adhesive. This container is carried by slide 33. Adjacent the outfeed end of the tipping machine. that is at the left in Figs. 11 and 12, are two presser members here taking the form of rolls 43 rotating in a horizontal plane and located above main bed 2O and adjacent to the lower ends of the signatures. These presser rolls are mounted on shaft 44 carried by slides adjustable in guides in exactly the same manner as the adhesive Chan` applying rolls. The parts may of course be driven by any suitable means, but, in the present instance the gearingis follows. Power is conveniently derived from the main shaft 45`of the gathering machine and is transmitted to a. transverse shaft 46 by means of bevel gears 47. 43 isan adhesive wheel driving shaft which receives its motion from shaft 46 by means of sprockets 49 and chain 50. Mounted on shaft 48 are adjustable spiral gears 51 engaging with similar gears 52 on shaft 37 on' which the adhesive applying wheels are mounted. Asimilar arrangement is used'to drive the presser rolls 43 in that gears on shaft 44 are driven from gears 54 adjustable on cross shaft 55, which latter carries a sprocket 56 driven by chain 57from sproclrl et 5S on shaft 48. Chain 13 of the gathering machine continues through the tipping machine and passes on its'upper run through guides 59 of the tipping machine, thence over idler 60 and down below'the machine, thence over sprocket 61 on shaft 46, over idler 62 and bach to the gathering machine.

From the foregoing it will be understood that the main signature group a and the end signatures are introduced in an ,upright position into the tipping machine preferably in one continuous action from thel gathering machine; signatures b and c occupying channels 6 and 7 a and group a occupyingthe space between the channels. At this time group a is at alower levelrl than level @of the channels as shown in Fig. 14. All the signatures are propelled by chain 13 and as the signature group passes between wheels 36 a line of adhesive is applied near the back of the outermost signatures thereof. Further advance of the signature group brings itto ramp 34 which elevates the group and brings it to the same level as the end signatures-in channels 6EL and 7, Before the narrowest point between pressure rolls 43 is reached the side walls of channels 6a and 721 terminate and the end signatures are pressed against the outer signatures of the signature group thereby causing them to adhere and all the signatures nowy pass as a unit out of the machine or they may pass to a binder such as that shown in Letters Patent No. 1,193,395, dated Aug. 1, 1916.

ln Figs. 15 to 17 inclusive a modified form of tipping machine is shown. vThe adhesive applying means are substantially the same as those previously described, but instead of bringing the signature group up a ramp to the level of the end signatures, the end signatures are brought down to the level of the signatureA group. This is accomplished by terminating the bottoms of channels 6b and 7 b at the point 63 a considerable dist-ance from the point where the presser members act on the signatures. To y assist the downward movement of the end signatures suckers 64 are provided. Each sucker is rotatably mounted on a shaft mounted in a bushing 66 and motion is imparted to it by means of a belt 67 passing from grooved friction disk 68 over idler 69 over disk 70 carried by shaft 65, over idler 7l and then back to disk 68. Shaft 65 is hollow and is connected to `a suotionl device that alternately exhausts and releasesthe air in well understood manner. In this form of the inventionl presser devices including parallel bars are used in place of rollers. Each of these devices is constructed as follows: 72 and 73 indicate two disks to which a bar71i is connected by means of Crank pins 75 and 76. Mounted on bar 74e is an adjustable plate 77 and carried by the latter is a presser element 7 8. Each disk carries aV spiral gear 7 9 and meshing with each ofsaid spiral gears is a. similar gear 80. Gears 8O are mounted on shaft 8l which latter also carries grooved disks 68. Motion is imparted to the presser device and the suckers by means of chain 82 from sprocket 58 and reaching to sprocket 83. Moving with sprocket 83 is a spiral gear 84 meshing directly with gear 7 9 of disk 73 on one side of the machine. Motion is transmitted from one shaft 8l to the other by means of sprockets 85 and chain 86.

As the signatures advance under the influence of the usual chain a line of adhesive is applied to the outer signatures ofthe main group, the end signatures are then brought down to the level of the main group and presser members 78 move inwardly and forwardly at the speed of the signatures and press them together.
